110:1-7 Christ's kingdom. - Glorious things are here spoken of Christ. Not only he should be superior to all the kings of the earth, but he then existed in glory as the eternal Son of God. Sitting is a resting posture: after services and sufferings, to give law, to give judgment. It is a remaining posture: he sits like a king for ever. All his enemies are now in a chain, but not yet made his footstool. And his kingdom, being set up, shall be kept up in the world, in despite of all the powers of darkness. Christ's people are a willing people. The power of the Spirit, going with the power of the world, to the people of Christs, is effectual to make them willing. They shall attend him in the beautiful attire of holiness; which becomes his house for ever. And he shall have many devoted to him. The dew of our youth, even in the morning of our days, ought to be consecrated to our Lord Jesus. Christ shall not only be a King, but a Priest. He is God's Minister to us, and our Advocate with the Father, and so is the Mediator between God and man. He is a Priest of the order of Melchizedek, which was before that of Aaron, and on many accounts superior to it, and a more lively representation of Christ's priesthood. Christ's sitting at the right hand of God, speaks as much terror to his enemies as happiness to his people. The effect of this victory shall be the utter ruin of his enemies. We have here the Redeemer saving his friends, and comforting them. He shall be humbled; he shall drink of the brook in the way. The wrath of God, running in the curse of the law, may be considered as the brook in the way of his undertaking. Christ drank of the waters of affliction in his way to the throne of glory. But he shall be exalted. What then are we? Has the gospel of Christ been to us the power of God unto salvation? Has his kingdom been set up in our hearts? Are we his willing subjects? Once we knew not our need of his salvation, and we were not willing that he should reign over us. Are we willing to give up every sin, to turn from a wicked, insnaring world, and rely only on his merits and mercy, to have him for our Prophet, Priest, and King? and do we desire to be holy? To those who are thus changed, the Saviour's sacrifice, intercession, and blessing belong.

Verse 4. - The Lord hath sworn, and he will not repent. "A fresh revelation" (Cheyne). David, admitted into the councils of the Most High, has been made aware that the Messiah is, by God's decree, to be both King and Priest. God has "sworn" this, and will certainly not draw back from his oath. Thou art a priest forever after the order of Melchizedek. Not, like ordinary priests, a priest for a few years, or for a lifetime, but a priest forever and ever (לעולם) - seeing "he ever liveth to make intercession for us" (Hebrews 7:25). And a priest "after the order of Melchizedek." Not, that is, after the order of Aaron, who was a priest and nothing more, but after that of Melchizedek, the elder priesthood, which combined the offices of priest and king (see Hebrews 5:6-10; Hebrews 7:1-10, 20-28).

The Lord hath sworn, and will not repent,.... What he swore about, and did not repent of, was the priesthood of Christ, as follows; and which shows the importance of it, since when Jehovah swears, as it is by himself, because he can swear by no greater; so it is about matters of great moment only that are sworn to by the Lord, as this of the priesthood of Christ was; which was concerned in things pertaining to God and his glory, as well as in making reconciliation for the sins of his people: and it shows the truth, and was for the confirmation of it; since doubts might arise whether the Aaronic priesthood was changed, seeing it was given to Phinehas for an everlasting priesthood; and since so great a person as the Son of God is said to be a priest; and since, in the human nature, he was of the tribe of Judah, of which tribe nothing was said concerning the priesthood: and this oath was not so much for Christ's sake, to establish the priesthood with him, and assure him of it, as for the sake of his people; who, by two immutable things, the word and oath of God, might have strong consolation from it; and it clearly shows the validity of his priesthood; that he was called of God to this office, and invested with it, and consecrated in it with an oath; and which is expressive of the singularity of it, and of the dignity and preference of the priesthood of Christ to that of Aaron's, Hebrews 7:20. What follows was said, and this oath was made, in the council of peace, when Christ was called to this office, and he accepted of it, Psalm 40:6, and of this the Lord never repented; as he never does of any of his acts of grace, Numbers 23:19.

Thou art a priest for ever after the order of Melchizedek; or, "according to the word of Melchizedek" (z); that is, according to what is said of him; there being an agreement between the things said of one and of the other; so the Syriac version, "according to the likeness of Melchizedek", see Hebrews 7:15 of him no mention is made elsewhere, but in Genesis 14:18 and in the epistle to the Hebrews. Various are the opinions of men concerning him: some think he was not a man, but an angel that appeared to Abraham: others, a divine power, superior to Christ, who were called "Melchizedecians": and others, that he was the Holy Ghost; and others, the Son of God himself, in an human form. On the other hand, some take him to be a mere man. The general notion of the Jews is, that he was Shem, the son of Noah; others, that he was a Canaanitish king, of the posterity of Ham: but others do not think it proper or lawful to inquire who he was, or from whom he descended; this being purposely hidden from men, that he might be more clearly a type of Christ. That there is a likeness between them is certain; the signification of his name, a title of office, King of righteousness, and King of peace, agrees with Christ the Lord, our righteousness and our peace: his being without father, mother, descent, beginning of days, and end of life, agree with the divinity, humanity, and eternity of Christ; and who is likewise King and Priest, as he was; and who blesses his people, as he did Abraham; and refreshes them with bread and wine, as he did Abraham's soldiers; See Gill on Hebrews 7:2. See Gill on Hebrews 7:3. Now Christ is a Priest like him; whose office is to offer sacrifice, which he has done, even himself, for the atonement of the sins of his people; to make intercession for them, which he ever lives to do; to introduce their persons to his Father, and present their petitions to him; and to call for every blessing for them, and answer all charges against them: in which office he continues for ever; there never will be any change in his priesthood, as there has been in Aaron's; nor will he ever have any successor: his priesthood is unchangeable, or does not pass from one to another, Hebrews 7:24, the efficacy of his blood and sacrifice always continues, and intercession is ever made by him, and the glory of his mediation is ever given him. The apostle produces this passage in proof of the change of the Aaronic priesthood, and so of the law, Hebrews 7:11 and about the time Christ appeared as the high priest, the legal priesthood sensibly declined, and which the Jews themselves own; for they say,

"after the death of Ishmael Ben Phabi, the splendour of the priesthood ceased (a);''

which man was made priest by Valerius Gratus, governor of Judea, under Tiberius Caesar (b),

4 The Lord hath sworn, and will not repent, Thou art a priest for ever after the order of Melchizedek.

We have now reached the heart of the Psalm, which is also the very centre and soul of our faith. Our Lord Jesus is a Priest-King by the ancient oath of Jehovah: "he glorified not himself to be made a high priest," but was ordained thereunto from of old, and was called of God a high priest after the order of Melchizedek. It must be a solemn and a sure matter which leads the Eternal to swear, and with him an oath fixes and settles the decree for ever; but in this case, as if to make assurance a thousand times sure, it is added, "and will not repent." It is done, and done for ever and ever; Jesus is sworn in to be the priest of his people, and he must abide so even to the end, because his commission is sealed by the unchanging oath of the immutable Jehovah. If his priesthood could be revoked, and his authority removed, it would be the end of all hope and life for the people whom he loves; but this sure rock is the basis of our security - the oath of God establishes our glorious Lord both in his priesthood and in his throne. It is the Lord who has constituted him a priest for ever, he has done it by oath, that oath is without repentance, is taking effect now, and will stand throughout all ages: hence our security in him is placed beyond all question.

The declaration runs in the present tense as being the only time with the Lord, and comprehending all other times. "Thou art," i.e., thou wast and art, and art to come, in all ages a priestly King. The order of Melchizedek's priesthood was the most ancient and primitive, the most free from ritual and ceremony, the most natural and simple, and at the same time the most honourable. That ancient patriarch was the father of his people, and at the same time ruled and taught them; he swayed both the sceptre and the censer, reigned in righteousness, and offered sacrifice before the Lord. There has never arisen another like to him since his days, for whenever the kings of Judah attempted to seize the sacerdotal office they were driven back to their confusion; God would have no king-priest save his son. Melchizedek's office was exceptional; none preceded or succeeded him; he comes upon the page of history mysteriously; no pedigree is given, no date of birth, or mention of death; he blesses Abraham, receives tithe, and vanishes from the scene amid honours which show that he was greater than the founder of the chosen nation. He is seen but once, and that once suffices. Aaron and his seed came and went; their imperfect sacrifice continued for many generations, because it had no finality in it, and could never make the comers thereunto perfect. Our Lord Jesus, like Melchizedek, stands forth before us as a priest of divine ordaining; not made a priest by fleshly birth, as the sons of Aaron; he mentions neither father, mother, nor descent, as his right to the sacred office; he stands upon his personal merits, by himself alone; as no man came before him in his work, so none can follow after; his order begins and ends in his own person, and in himself it is eternal, "having neither beginning of days nor end of years." The King-priest has been here and left his blessing upon the believing seed, and now he sits in glory in his complete character, atoning for us by the merit of his blood, and exercising all power on our behalf.

4. The perpetuity of the priesthood, here asserted on God's oath, corresponds with that of the kingly office just explained.

after the order—(Heb 7:15) after the similitude of Melchisedek, is fully expounded by Paul, to denote not only perpetuity, appointment of God, and a royal priesthood, but also the absence of priestly descent and succession, and superiority to the Aaronic order.

You are a Priest Forever…3Your people will volunteer freely in the day of Your power; In holy array, from the womb of the dawn, Your youth are to You as the dew. 4The LORD has sworn and will not change His mind, "You are a priest forever According to the order of Melchizedek."5The Lord is at Your right hand; He will shatter kings in the day of His wrath.…
